ATTACHMENT FOR COLLAPSIBLE TUBES.

Specification of Letters Patent. i Fatentgd July 23?, 15915 3.,

Application filed April 30, 1914. Serial No. 835,501.

To all whom it may concern:

Be it known that I, Thomas C. BOOTH, a citizen of the United States of America, and resident of the borough of Manhattan, in the city of New York, county and State of New York, have invented certain new and useful Improvements in Attachments for Collapsible Tubes, of which the following isa specification, p

This invention relates to collapsible tubes for tooth-pastes, paints, cold creams, vaseline, cement and the like, and more particularly to attachments therefor, the object of the invention being to provide an improved attachment for collapsible tubes the use of which insures the regular and uniform expulsion of the contents of the collapsible tube during its use, and at the same time aiiords improved means intended to be used for advertising and displaying purposes.

A further object of, the invention is to provide such an attachment which operates to prevent the mashing or undesired collapsing of the tube, as happensby' the handling of the tubes either in transit or when on display, by meansofwhich unequal indentations the use of the tube is seriously affected.

My invention is shown in the accompanying drawingand will be more fully described hereinafter and finally pointed out in the claim.

In the accompanying drawing, Figure 1 is a front-view-of my improved attachment applied to a collapsible tube, Fig. 2 is a side-view thereof, Fig: 3 is a vertical central section through the tube and the attachment, and Figs. 4 and 5 are respectivel i horizontal sections on line and 5-5 0 Fig. 1.

Similar referenceharacters indicate corresponding parts throughoutthe several fig- 'ures of the'drawing.

Referring to the drawing, and more particularly to Figs. 1 and 2, the collapsible by 10, which collapsible tube has the threaded neck 11. Gr, the neck may bemade plain, or in any desired shape. The cap 15 is placed upon the neck 11, and closes the tube; removal of the cap permits the removal of the contents of the tube as is well known. This neck with its screwthreads and this cap with the screw-threads engaging therewith, may be of any suitable construction or design, and may be varied as desired.

The collapsible tubes as shown in the drawing and as described are well known in the art and form no part of this inven tion.

In order to prevent an unequal and irregular discharge of the contents from the tube, my invent-ion provides an attachment which consists of opposed compression members arranged longitudinally to the tube at opposite sides of the same. in the em.- bodiment shown, a strip of heavy cardboard is provided at its middle with an opening 18, by which the strip is slipped upon the neck of the tube, the cap having been first removed. After the attachment is in place the cap is replaced, and holds the attachment securely at that end of the tube.

The two free portions 20 and 21 which then depend along opposite sides of the tube converged in their lower parts to conform to the taper of the tube and united'at their lower ends. These ends, when there is a joint between them, may if desired be clenched in with the metal of the tube as shown at 19in Figs. 2 and 3. As shown in Figs. ,4 and 5, they lie at opposite sides of the tube, and are tangential thereto, and

parallel to each other, and are of a width greater than the diameter ctthe tube itself. Their width is approximately the same as that of the tube in its fiattened condition after use. In place of cardboard, any other comparatively still, yet not entirely inflexible material, may be used for making the attachment. I

By this attachment, as is seen in Figs. 1 and 2, the walls ofthe collapsible tube are protected in an efficient mannenin that any undesired indentation of the tube or unequal pressing thereon is prevented. The compression-members 20, 21, of the attachment, when a desired pressure is exerted thereon, transfer this pressure in an equal and regular manner onto the walls of'the tube and onto the material therein, whereby a regular and uniform flow oi the contents unequal iudenilaiiori thereof. she unequal indentation is sailed for instance often happens an she c i by o user and part was the orifice, when the e onfithc contours at that par?u forces consents oui; of

vertising matter upon the attachment described is less expensive, and enables better effects to be produced, than when the same is placed upon the tube itself.

A further function of the attachment is that; one surface thereof may be used as an addressing card on which the address of the intended consumer is Writtem and the tube may then i transmission to destination.

The two parallel Walls with one end fastened and one end provided with amopening for the passage of the neck of the container, may readily iii "l-application also in connection with small glass vials or bottles, for instance, as are used for gold or gilt dust paints, which thereby would act to prevent the breakage thereof, and at the same time as an advertising medium, and also prevent to a certain extent the rolling of the bottles when they are made in cylindrical shape and hold them in position during the use thereof.
